Omenn Sendromlu Bir Olgu

Year 2013, Volume: 7 Issue: 1, 40 - 43, 01.04.2013

Abstract

Omenn Sendromu otozomal resesif geçişli, büyüme geriliği, eritrodermi, inatçı diyare, lenfadenopati, hepatosplenomegali, tekrarlayan şiddetli enfeksiyonlarla karakterize ağır kombine immün yetmezliğin bir formudur. Lenfosit panelinde dolaşımdaki T lenfositler normal olmasına karşın, fonksiyonları bozuktur. Dolaşımdaki B lenfositler ise azalmış ya da yoktur. Olgumuz 29 yaşındaki gestasyonel diyabetik annenin 37 haftalık ikinci gebeliğinden ilk yaşayan olarak doğan kız bebek olup, 2 yıl önce Omenn sendromu nedeniyle 51 günlükken kaybedilmiş kız kardeş öyküsü vardı. Ailede tanımlanmış akrabalık yoktu. Hastanın fizik muayenesinde tüm vücutta yaygın eksfoliyatif karakterde eritrodermi dışında patoloji saptanmadı. Rutin tetkiklerinde, eozinofili mevcuttu. Posteroanteriyor akciğer grafisi, batın ve kraniyal ultrasonografi, ekokardiyografi sonuçları normaldi. IgG normalin alt sınırında, IgA ve M düşük, lenfosit panelinde aktive T lenfosit artışı ve B lenfositlerde ileri derecede düşüklük saptandı. Daha önce kardeşinde yapılan genetik değerlendirmede homozigot RAG1 g.854C>T (p.Q248X) mutasyonu saptanan hastanın, anne ve babası da aynı mutasyonu heterozigot olarak taşımakta olup, hastamızda da homozigot RAG1 g.854C>T mutasyonu saptandı. Hastanın anne ve babasının immünglobulin düzeyleri ve lenfosit panellerinin normal olması üzerine babadan haploidantik kök hücre nakli yapıldı. Ancak hasta transplant sonrası 12. günde enfeksiyon nedeniyle kaybedildi.Omenn sendromu tedavi edilmezse fatal bir hastalık olup, uygun kemik iliği transplantasyonu ya da kord kanı kök hücre transplantasyonu ile tedavi edilebilen bir hastalık olması dolayısıyla, genetik danışma büyük önem taşımaktadır.

A Case with Omenn Syndrome

Year 2013, Volume: 7 Issue: 1, 40 - 43, 01.04.2013

Abstract

The Omenn syndrome is a form of severe combined immune deficiency that is inherited autosomal recessively and characterized by growth retardation, erythrodermia, lymphadenopathy, hepatosplenomegaly and severe recurrent infections. Although circulating T lymphocytes on the lymphocyte panel are normal, their functions are abnormal. On the other hand, circulating B lymphocytes are decreased or absent. Our case was a baby girl who was born to the second pregnancy of a 29-year-old mother on the 37th gestational week. She had a history of a sister’s death on the 51st day of life due to Omenn syndrome. There was no consanguinity between parents. Her physical examination was normal expect generalized exfoliative erythrodermia. Routine laboratory investigations revealed eosinophilia. X-ray, echocardiography, abdominal and transfontanel ultrasonography findings were normal. IgG was at the lowest boundaries of the normal values. IgA and IgM were low as well. While T lymphocytes were elevated, B lymphocytes were extremely low. The family had a history of a baby death with the homozygote RAG1 g.854C>T (p.Q248X) mutation and parents were heterozygote carriers of the same mutation. Our patient also had the same homozygote RAG1 g.854C>T mutation. Since the parents’ immunoglobulin levels and lymphocyte panels were normal, haploidentical stem cell transplantation from the father was performed. Unfortunately our patient passed away due to pulmonary infection on the posttransplantation 12th day.Genetic counseling has a great significance as untreated Omenn syndrome is fatal but the disorder is treatable with appropriate bone marrow or umbilical cord blood stem cell transplantion

The publication language of Turkish Journal of Pediatric Disease is English.


Manuscripts submitted to the Turkish Journal of Pediatric Disease will go through a double-blind peer-review process. Each submission will be reviewed by at least two external, independent peer reviewers who are experts in the field, in order to ensure an unbiased evaluation process. The editorial board will invite an external and independent editor to manage the evaluation processes of manuscripts submitted by editors or by the editorial board members of the journal. The Editor in Chief is the final authority in the decision-making process for all submissions. Articles accepted for publication in the Turkish Journal of Pediatrics are put in the order of publication, with at least 10 original articles in each issue, taking into account the acceptance dates. If the articles sent to the reviewers for evaluation are assessed as a senior for publication by the reviewers, the section editor and the editor considering all aspects (originality, high scientific quality and citation potential), it receives publication priority in addition to the articles assigned for the next issue.


The aim of the Turkish Journal of Pediatrics is to publish high-quality original research articles that will contribute to the international literature in the field of general pediatric health and diseases and its sub-branches. It also publishes editorial opinions, letters to the editor, reviews, case reports, book reviews, comments on previously published articles, meeting and conference proceedings, announcements, and biography. In addition to the field of child health and diseases, the journal also includes articles prepared in fields such as surgery, dentistry, public health, nutrition and dietetics, social services, human genetics, basic sciences, psychology, psychiatry, educational sciences, sociology and nursing, provided that they are related to this field. can be published.
